For the year 2004, 251 supernovae have been reported (338 last year).   66 in NGC and IC galaxies (73 last year), 126 got brighter than 18th Mag (148 last year).  26 extragalactic novae were also reported.  The brightest supernova reported for the year is 2004dj at mag 11.2, followed by 2004et at mag 12.3, and 2004gk at mag 13.3.

Interesting events in 2004
• 2004dj in nearby NGC 2403 reached Mag 11.2 (type IIn).   This was the brightest supernova since 1987A.
• Our most active galaxy, NGC 6946 had it's 8th supernova, 2004et which reached Mag 12.3
• We have two supernovae in Messier galaxies.
  • 2004W in M60 (type Ia found after solar conjunction, probably a 1/2 year old at discovery)
  • 2004am in M82 (found by image subtraction, in an HII region in this very active galaxy)
